CROSS-REFERENCE TO RELATED APPLICATION

This application is a divisional of U.S. application Ser. No. 17/010,336, filed on Sep. 2, 2020, which claims priority to and the benefit of Korean Patent Application No. 10-2019-0108168, filed on Sep. 2, 2019, the disclosures of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The present disclosure relates to a home appliance and a mobile terminal including an application for registering the home appliance in a server, and a pre-registered home appliance registering an unregistered home appliance in the server and a mobile terminal including an application registering the unregistered home appliance in the server.

BACKGROUND

With the popularization of mobile terminals such as smart phones and development of Internet of Things (IoT) technology, home appliances performing communication may be used increasingly.

Home appliances may be connected to a server or a mobile terminal through an access point (AP) such as a router at home to perform the communication function. In addition, users may easily determine a state of the home appliance using the mobile terminal and may also remotely control an operation of the home appliance. Furthermore, the users may easily perform product registration of the home appliance using the mobile terminal.

Conventional systems may disclose a mobile terminal, a communication device capable of receiving remote control information and power information of a home appliance, and an operation method thereof. For example, the mobile terminal connects to the communication device based on network identifier information received from the communication device, receives product information of the home appliance from the communication device, and then transmits the received product information to a server, to easily perform the product registration of the home appliance. By way of further example, the mobile terminal may scan an AP device connected to the communication device among neighboring AP devices to remotely control the home appliance and the users may accurately input network information (e.g., a password) of the AP device connected to the communication device.

The home appliance may be registered through the above method, which causes a lot of battery consumption of the mobile terminal due to the scan operation performed on the AP device. The product registration may fail if the users incorrectly input the network information (e.g., the password) of the AP device.

SUMMARY

The present disclosure is directed to a home appliance and a mobile terminal. An operation of searching for an unregistered home appliance is performed by a pre-registered home appliance, not by a mobile terminal.

The present disclosure also is directed to a home appliance and a mobile terminal to transmit, to an unregistered home appliance, network information that has already been used when registering a pre-registered home appliance through communication between home appliances, without additional user input.

According to one aspect of the subject matter described in this application, a home appliance configured to be registered in a server includes a wireless fidelity (Wi-Fi) module, based on the home appliance being registered in the server, communicatively connected to an access point (AP) and configured to periodically operate in an AP mode through a virtual interface, and a controller configured to control the Wi-Fi module to periodically operate in the AP mode. The Wi-Fi module may be configured to generate a beacon signal to search for an unregistered home appliance based on the Wi-Fi module being operated in the AP mode.

The controller 160 b may include at least one CPU, the microcomputer, the processor, and the IC.

In some examples, the pre-registered home appliance 10 b is already registered in the server 40 and may communicate with the user AP 30, and thus, the user may control the pre-registered home appliance 10 b using the service provided by the home appliance control system.

Further, the Wi-Fi module 112 b of the pre-registered home appliance 10 b may include a virtual interface 113 b. In this example, the pre-registered home appliance 10 b may communicate with two devices at the same time by using the Wi-Fi module 112 b with the virtual interface 113 b.

For example, the virtual interface 113 b is a virtual interface added by time-dividing one physical Wi-Fi interface. The Wi-Fi module 112 b may perform a communication function as if two physical Wi-Fi interfaces are operated through the virtual interface 113 b.

In this example, the pre-registered home appliance 10 b includes the Wi-Fi module 112 to communicate with the user AP 30 to obtain information regarding the user AP 30 and the virtual interface 113 b to periodically operate the Wi-Fi module 112 in the AP mode. In addition, when the Wi-Fi module 112 b is operated in the AP mode, the Wi-Fi module 112 b generates a beacon signal to search for a neighboring unregistered home appliance and may use the hidden SSID. For example, the hidden SSID information may be included in the beacon signal.

In some implementations, the Wi-Fi module 112 b may be communicatively connected to the unregistered home appliance 10 a that recognizes the hidden SSID by using the virtual interface 113 b. In this case, the communication connection may be controlled by the controller 160 b.

In some implementations, the Wi-Fi module 112 b may receive a push signal from a communicatively-connected unregistered home appliance 10 a and may provide a communicatively-connected unregistered home appliance 10 a with information regarding the user AP 30.

For example, the pre-registered home appliance 10 b may be communicatively connected to the unregistered home appliance 10 a through the virtual interface 113 b while maintaining the communication connection with the user AP 30.

Detailed implementations are described below with respect to FIGS. 6 to 15 .

FIG. 4 is an exemplary block diagram depicting the mobile terminal in FIG. 1 .

Referring to FIG. 4 , a mobile terminal 20 may include a wireless communicator 210, an input unit 220, an output unit 230, a memory 240, and a controller 250. The components thereof depicted in FIG. 4 are not example components for implementing the mobile terminal 20 and the mobile terminal 20 may include more or fewer components.

The wireless communicator 210 may include at least one communication module to execute communication connection between the mobile terminal 20 and the server 40. For example, the wireless communicator 210 may include a mobile communication module 212 using long term evolution (LTE), a Wi-Fi module 214, other short-range communication modules, or a wireless Internet module.

The input unit 220 may include an image input unit (e.g., a camera) to receive a video signal, a microphone to receive an audio signal, an audio input unit, or a user input unit to receive information from a user (e.g., a touch key and a push key (e.g., a mechanical key)).

The output unit 230 generates output in the form of visual, auditory, or tactile manner. For example, the output unit 230 may include a display unit 232 and an audio output unit 234.

In some examples, the display unit 232 may be stacked with a touch sensor to form a layer structure or may be integrated with the touch sensor to implement a touch screen. The touch screen functions as a user input unit to provide an input interface between the mobile terminal 20 and the user (e.g., to receive a touch input from a user) and also provides an output interface between the mobile terminal 20 and the user.

For example, an image displayed on the display unit 232 may be controlled by the controller 250 and the display unit 232 may provide the controller 250 with the touch input received from the user.

The memory 240 may store data used to support various functions of the mobile terminal 20. The memory 240 may store a number of applications executed on the mobile terminal 20, data, commands, and a hidden SSID list for operation of the mobile terminal 20. At least a portion of the applications may be downloaded from external servers via wireless communication.

The controller 250 may control overall operation of the mobile terminal 20.

The controller 250 may process signals, data, information, and the like input or output by the above components or may execute an application stored in the memory 240, thereby providing appropriate information to a user or processing appropriate functions.

For example, the controller 250 of the mobile terminal 20 may drive an appliance control application (APP) 260. The appliance control APP 260 may control a home appliance (e.g., a pre-registered home appliance 10 b) registered on a service provided by the home appliance control system.

The appliance control APP 260 may be downloaded from the server 40 or a server providing an application download service and may be stored in the memory 240.

The user may perform various managements such as controlling the pre-registered home appliance 10 b using the appliance control APP 260, registering the unregistered home appliance 10 a on the service, or removing the pre-registered home appliance 10 b from the service.

For example, when the appliance control APP 260 is executed, the pre-registered home appliances may be automatically or manually searched. For example, pre-registered home appliances may be automatically searched based on the beacon signal generation.

In some examples, all pre-registered home appliances operating in the AP mode and all pre-registered home appliances connected to the same user AP 30 similar to the mobile terminal 20 may be searched. The hidden SSID may match a hidden SSID in the list stored in the memory 240 of the mobile terminal 20.

In addition, all pre-registered home appliances searched by the mobile terminal 20 may provide the mobile terminal 20 with a push signal. In this case, the controller 250 of the mobile terminal 20 controls the display unit 232 to display a communication connection selection screen of the pre-registered home appliance based on the push signal of the pre-registered home appliance and controls the input unit 220 or the display unit 232 to receive, from the user, the communication connection selection input for the pre-registered home appliance. In addition, the controller 250 may control the display unit 232 to display a registration confirmation key input guide screen of the pre-registered home appliance based on the received communication connection selection input. When the user completes the registration confirmation key input to the pre-registered home appliance, the pre-registered home appliance may be immediately controlled by the appliance control APP 260.

The home appliance control system may include the above-described configuration and features. Hereinafter, the home appliance 10 a registered on a home appliance control service provided by the home appliance control system will be described with respect to FIGS. 5 to 15 .

FIG. 5 is an exemplary ladder diagram depicting an unregistered home appliance registration service of the home appliance control services in FIG. 1 .

Hereinafter, for the convenience of description, a home appliance 10 registered or controlled by users may also refer to a product.

In addition, the implementation is described in which the product 10 is communicatively connected to other products and the user AP 30 by using the Wi-Fi modules 112 a and 112 b, but the present implementations is not only limited to the Wi-Fi modules 112 a and 112 b and may be applied to a wireless communication module to support other similar wireless communication schemes.

Hereinafter, controllers 160 a and 160 b of the product 10 are described as controlling the operations of Wi-Fi modules 112 a and 112 b, but the operation of each of the Wi-Fi modules 112 a and 112 b may also be controlled by a microcomputer of each of the Wi-Fi modules 112 a and 112 b. For example, the controllers 160 a and 160 b of the product 10 may include a main controller of the product 10 and the microcomputer of the Wi-Fi modules 112 a and 112 b.

Referring to FIG. 5 , the pre-registered home appliance 10 b generates a beacon signal (S100).

In some examples, the controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to obtain information regarding the user AP from the user AP 30 and periodically operate in an AP mode. The Wi-Fi module 112 b receives the information regarding the user AP 30 from the user AP 30.

The Wi-Fi module 112 b may generate a beacon signal to search for a nearby unregistered home appliance 10 a when the Wi-Fi module 112 b operates in the AP mode. In some implementations, the Wi-Fi module 112 b may use a hidden SSID when the Wi-Fi module 112 b operates in the AP mode.

The unregistered home appliance 10 a may detect the beacon signal (S120).

In some examples, the controller 160 a of the unregistered home appliance 10 a may control the Wi-Fi module 112 a to search for the pre-registered home appliance 10 b that transmits the beacon signal.

For example, the controller 160 a of the unregistered home appliance 10 a may control the Wi-Fi module 112 a to search for the pre-registered home appliance 10 b to transmit the beacon signal when a specific event (e.g., a turn-on of a washing machine) occurs.

When detecting the beacon signal, the Wi-Fi module 112 a may search for the pre-registered home appliance 10 b to transmit the beacon signal based on the detected beacon signal.

When the beacon signal is detected (S120), the unregistered home appliance 10 a may determine whether the hidden SSID of the searched pre-registered home appliance 10 b matches the preset hidden SSID stored in the list (S140).

In some examples, the memory 150 a of the unregistered home appliance 10 a may store a preset hidden SSID list. The preset hidden SSID list may be a list recording a plurality of hidden SSIDs used for products manufactured by a specific manufacturer.

In this example, the controller 160 a may compare the hidden SSID of the pre-registered home appliance 10 b searched by the Wi-Fi module 112 a with the preset hidden SSID in the list stored in the memory 150 a and may determine whether the hidden SSID of the pre-registered home appliance 10 b searched by the Wi-Fi module 112 a matches the preset hidden SSID in the list stored in the memory 150 a based on the comparison result.

Then, if the hidden SSID of the searched pre-registered home appliance 10 b matches the preset hidden SSID stored in the list, the unregistered home appliance 10 a may request a communication connection to the pre-registered home appliance 10 b (S160).

In some examples, when the controller 160 a determines that the hidden SSID of the searched pre-registered home appliance 10 b matches the preset hidden SSID stored in the list, the controller 160 a may control the Wi-Fi module 112 a to attempt the communication connection (e.g., to transmit the connection request) with the searched pre-registered home appliance 10 b.

In some implementations, when the virtual interface 113 b of the Wi-Fi module 112 b receives the communication connection request from the unregistered home appliance 10 a that has recognized the hidden SSID, the controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to communicatively connect with the unregistered home appliance 10 a that has recognized the hidden SSID.

When the unregistered home appliance 10 a and the pre-registered home appliance 10 b are communicatively connected through the above process, the unregistered home appliance 10 a may transmit a push signal to the pre-registered home appliance 10 b (S180).

For example, when the Wi-Fi module 112 a of the unregistered home appliance 10 a is communicatively connected to the searched pre-registered home appliance 10 b, the controller 160 a of the unregistered home appliance 10 a may control the Wi-Fi module 112 a to transmit the push signal to the communicatively-connected pre-registered home appliance 10 b.

When the Wi-Fi module 112 b receives the push signal from the communicatively-connected unregistered home appliance 10 a, the controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to transmit the push signal to the server 40 through the user AP 30.

In addition, the server 40 may transmit the push signal received through the user AP 30 to the mobile terminal 20 and the mobile terminal 20 may receive the push signal of the unregistered home appliance 10 a by using the Wi-Fi module 214.

Through this process, the push signal may be transmitted from the unregistered home appliance 10 a to the mobile terminal 20.

When the mobile terminal 20 receives the push signal, the mobile terminal 20 may display a connection selection screen of the unregistered home appliance 10 a (S200).

In some examples, the controller 250 of the mobile terminal 20 may control the display unit 232 to display the connection selection screen of the unregistered home appliance 10 a based on the push signal of the unregistered home appliance 10 a.

For example, when the controller 250 of the mobile terminal 20 receives the push signal of the unregistered home appliance 10 a by using the Wi-Fi module 214, the controller 250 may execute the appliance control APP 260 based on the push signal. Then, as the appliance control APP 260 is executed, the controller 250 may control the display unit 232 to display an execution screen of the APP 26A) (e.g., a connection selection screen of the unregistered home appliance 10 a).

FIG. 6 depicts an example of a connection selection screen 500 of an unregistered home appliance 10 a displayed on a display unit 232.

When the connection selection screen is displayed on the display unit 232, the display unit 232 of the mobile terminal 20 may receive a connection selection input from the user (S220).

In some examples, when the user touches a “connection” portion of the connection selection screen 500 depicted in FIG. 6 , the display unit 232 of the mobile terminal 20 may receive the connection selection input. In some implementations, the display unit 232 may provide the controller 250 with the received connection selection input.

For example, the user may touch the “connection” portion of the connection selection screen 500 within a predetermined time period.

If the user does not touch “the connection” of the connection selection screen 500 within the predetermined time period, the display unit 232 of the mobile terminal may display all communicable unregistered home appliance list selection screen 540 (see FIG. 10 ) including the unregistered home appliance 10 a. “When the user does not touch within the predetermine time period” corresponds to “when the controller 250 does not receive the connection selection input to the unregistered home appliance 10 a by using the display unit 232 within the predetermined time period”. Details thereof are described below.

When the connection selection input is provided to the controller 250, the mobile terminal 20 may transmit a registration confirmation request to the server 40 (S240).

In some examples, the controller 250 of the mobile terminal 20 may control the Wi-Fi module 214 to transmit, to the server 40, the registration confirmation request for the unregistered home appliance 10 a based on the connection selection input received from the display unit 232.

The controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to receive the registration confirmation request for the unregistered home appliance 10 a from the server 40 connected to the user AP 30. In this case, the controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to transmit the registration confirmation request to the unregistered home appliance 10 a. In some examples, the unregistered home appliance 10 a may receive the registration confirmation request from the pre-registered home appliance 10 b by using the Wi-Fi module 112 a.

The registration confirmation request may be transmitted from the mobile terminal 20 to the unregistered home appliance 10 a through the above process.

When the registration confirmation request is transmitted from the mobile terminal 20 to the server 40, the mobile terminal 20 may display a registration confirmation key input guide screen of the unregistered home appliance 10 a (S260).

In some examples, the controller 250 of the mobile terminal 20 may control the display unit 232 to display the registration confirmation key input guide screen of the unregistered home appliance 10 a.

For example, the registration confirmation key input guide screen 510 may display the phrase “Please press a XXX button of the unregistered home appliance 10 a for 3 seconds or more”.

When the registration confirmation key input guide screen 510 is displayed, an input unit 120 a of the unregistered home appliance 10 a may receive a registration confirmation key input from a user (S280).

In some examples, when the user inputs the registration confirmation key to the unregistered home appliance 10 a using the method depicted in FIG. 7 , the input unit 120 a of the unregistered home appliance 10 a may receive a registration confirmation key input. Then, the input unit 120 a may provide the controller 160 a with the received registration confirmation key input.

When the controller 160 a receives the registration confirmation key input, the controller 160 a of the unregistered home appliance 10 a may transmit the registration confirmation key input completion signal to the pre-registered home appliance 10 b (S300).

In some examples, the controller 160 a of the unregistered home appliance 10 a may control the Wi-Fi module 12 a to receive the registration confirmation request from the pre-registered home appliance 10 b. Then, when the registration confirmation key input from the user is determined, the controller 160 a of the unregistered home appliance 10 a may control the Wi-Fi module 112 a to transmit the registration confirmation key input completion signal to the pre-registered home appliance 10 b.

When the Wi-Fi module 112 b receives the registration confirmation key input completion signal from the unregistered home appliance 10 a, the controller 160 b of the pre-registered home appliance 10 b may control the Wi-Fi module 112 b to transmit the registration confirmation key input completion signal to the server 40 through the user AP 30.

In some implementations, the controller 250 of the mobile terminal 20 may control the Wi-Fi module 214 to receive the registration confirmation key input completion signal from the server 40.

For example, when the Wi-Fi module 214 does not receive a signal related to success or failure of registration of the unregistered home appliance 10 a after receiving the registration confirmation key input completion signal from the server 40, the controller 250 of the mobile terminal 20 may control the display unit 232 to display a registration progress screen of the unregistered home appliance 10 a.

FIG. 8 shows an example of a registration progress screen 520 of an unregistered home appliance 10 a displayed on a display unit 232.

When the Wi-Fi module 214 receives, from the server 40, the registration failure signal of the unregistered home appliance 10 a, the controller 250 of the mobile terminal 20 may control the display unit 232 to display a screen including the reason for registration failure of the unregistered home appliance 10 a based on the registration failure signal.

Then, when the input unit 220 or the display unit 232 receives the user's registration retry selection input for the unregistered home appliance 10 a based on the screen including the reason for registration failure, the controller 250 of the mobile terminal 20 may control the display unit 232 to display an existing product registration guide screen based on the received registration retry selection input.

For example, the existing product registration guide screen may include, for example, screens depicted in FIGS. 11 to 13 .

If the user fails to touch “the connection” of the connection selection screen 500 (see FIG. 6 ) within a predetermined time period at S220, the display unit 232 of the mobile terminal 20 may display all communicable unregistered home appliance list selection screen 540 (see FIG. 10 ) including the unregistered home appliance 10 a. In this case, “w % ben the user fails to touch within a predetermined time period” corresponds to “when the controller 250 fails to receive the connection selection input to the unregistered home appliance 10 a through the display unit 232 within a predetermined time period”.

FIG. 10 depicts an exemplary communicable unregistered home appliance list screen 540.

For example, a controller 250 of a mobile terminal 20 may control an appliance control APP 260 to display, on a display unit 232, a communicable unregistered home appliance list selection screen 540 including an unregistered home appliance 10 a.

For example, the screen 540 may display connectable unregistered home appliance list (e.g., Device 1, Device 2, and Device 3), as well as various product line options (e.g., a household appliance—a general washing machine, a drum washing machine; a kitchen appliance—a refrigerator).

When the user touches the unregistered home appliance 10 a (e.g., Device 1) on the communicable unregistered home appliance list selection screen 540, the display unit 232 of the mobile terminal 20 may receive the connection selection input for the unregistered home appliance 10 a (e.g., Device 1). The display unit 232 may provide the controller 250 with the received connection selection input.

For example, when the controller 250 receives the connection selection input for the unregistered home appliance 10 a from the display unit 232, the controller 250 of the mobile terminal 20 may control the display unit 232 to display an existing product registration guide screen or a registration guide screen for the unregistered home appliance 10 a based on the received connection selection input.

The existing product registration guide screen may include, for example, screens depicted in FIGS. 11 to 13 .

In some examples, the controller 250 of the mobile terminal 20 may display a screen 550 requesting the user to activate the Wi-Fi module 112 a of the unregistered home appliance 10 a.

When the user activates the Wi-Fi module 112 a of the unregistered home appliance 10 a, the Wi-Fi module 112 a of the unregistered home appliance 10 a may be switched to an AP mode. As the Wi-Fi module 112 a is switched to the AP mode, the Wi-Fi module 214 of the mobile terminal 20 may access the Wi-Fi module 112 a of the unregistered home appliance 10 a.

Referring to FIGS. 12 and 13 , when the mobile terminal 20 and the unregistered home appliance 10 a are connected based on the connection result, the controller 250 may display screens to obtain information regarding user AP 30 for transmitting to the unregistered home appliance 10 a.

For example, the controller 250 may control the AP selection screen 560 depicted in FIG. 12 to receive the selection input for the user AP 30 to connect with the unregistered home appliance 10 a in the list including at least one AP. For example, when the user selects an item 562 with the name of ‘AAA’, corresponding to the user AP 30, the controller 250 may control the Wi-Fi module 214 to transmit the information regarding the user AP 30 to the unregistered home appliance 10 a.

According to some implementations, when a password is needed for connecting to the selected user AP 30, the controller 250 may control a display unit 232 to display a password input window 570 to obtain the password of the user AP 30 as depicted in FIG. 13 . The user may enter a password to a password input tab 572 of the password input window 570 and the controller 250 may control the Wi-Fi module 214 to transmit, to the unregistered home appliance 10 a, the information on user AP including the input password.

In this case, the unregistered home appliance 10 a may be communicatively connected to the corresponding user AP 30 based on information regarding the user AP 30 received from the mobile terminal 20 and may be registered in the server 40 through the user AP 30 communicatively connected to the unregistered home appliance 10 a.

In some examples, the re-registration guide screen for the unregistered home appliance 10 a may include, for example, screens depicted in FIGS. 14 and 15 .

In some examples, a controller 250 of the mobile terminal 20 may display a screen 580 requesting a user to switch to a client mode (e.g., reboot) of the unregistered home appliance 10 a.

When the unregistered home appliance 10 a is switched to the client mode, the unregistered home appliance 10 a may transmit a client mode switch completion signal to the pre-registered home appliance 10 b, the pre-registered home appliance 10 b may transmit the client mode switch completion signal to the server 40 through the user AP 30, and the server 40 may transmit the client mode switch completion signal to the mobile terminal 20.

In this case, the controller 250 of the mobile terminal 20 may control the Wi-Fi module 214 to transmit, to the server 40, the registration confirmation request for the unregistered home appliance 10 a based on the received client mode switch completion signal and may control the display unit 232 to display the registration confirmation key input guide screen of the unregistered home appliance 10 a.

Thereafter, steps S280 to S420 described above with respect to FIG. 5 may be applied.

The home appliance control system performs the unregistered home appliance registration service to improve a registration mechanism of the unregistered home appliance.

According to some implementations, the home appliance control system performs the operation of searching for the unregistered home appliance by using the pre-registered home appliance, not by the mobile terminal, to limit battery consumption of the mobile terminal due to the scan operation performed on the AP device.

In addition, according to some implementations, the home appliance control system may transmit, to the unregistered home appliance, the network information already used when registering the pre-registered home appliance through communication between the home appliances, without additional user input, to improve a product registration success rate.
